The hypothesis is that the Mariotte Siphon will apply fertilizers to a field in a constant and uniform manner.

You will peel the label off of a 2-liter bottle, cut a small hole in the side of the bottle, seal the edges around the straw with Shoe Goo, drill a hole in the cap of the bottle, fill the bottle with water, and measure the flow rate of the siphon.

You will need a 2-liter bottle with cap, an exacto knife, a small drill, Shoe Goo, a small round tube about 2 inches long, a plastic tube from a Windex bottle, a stop watch, and a graduated cylinder.

This project demonstrates how to construct a Mariotte Siphon, a device that will apply fertilizers to a field in a constant and uniform manner. The flow rate of the siphon can be measured and the shape of the jet of water exiting the siphon can be observed. This device is useful for applying liquid fertilizer to field crops in a uniform manner, reducing the chance of overfertilizing and contaminating the groundwater.

This science project is unique because it teaches students how to construct a device that can be used to apply fertilizers to a field in a consistent and uniform manner.

Experiment variations to consider include measuring the flow rate of the siphon with different vent tubes and observing the shape of the jet of water exiting the siphon when the vent tube is removed.
